Universities have recently introduced problem-based learning (PBL) to various subjects to enhance problem-solving skills (including self-directed learning and small-group learning) required in industry. The PBL module was applied to the personal production process in a draping class. A study was based on a questionnaire after conducting two PBL modules with a group of students. Each PBL module included 'design analysis', 'presentation of flat sketch and draping plan', 'discussion of the plan', 'evaluation of the draping result and correcting the problem', and 'final evaluation of the completed project'. Results showed that satisfaction with the PBL method and its activities was higher than satisfaction with existing teaching methods. In particular, among the various components, the 'design analysis' and 'the presentation step of flat sketch and draping plan' stages were more helpful to students compared to small-group discussion. Moreover, the effects of PBL were observed through student reflection essays, in which students suggested that PBL was very effective in enhancing problem-solving through self-directed and small-group learning. Despite the overall satisfaction with PBL, students expressed some minor difficulties associated with awkwardness with a novel learning method, lack of diverse perspectives among each group, and poor communication skills. Therefore, the study shows that PBL is highly likely to be useful to students when they are solving pattern drafting problems and making samples through self-directed learning and small-group learning.

The purpose of this study is to create a planting design for progressive realization. For this, visual preferences as measured via questionnaire were evaluated by the Scenic Beauty Estimation(SBE) and paired comparison methods. The results can be summarized as follows. Through photo observation, the average visual blockage ratio was 38% and the range of degree of the visual blockage ratio was $30{\sim}50%$. The sketch simulation and filtered pattern received the highest preference score and fumed out to be the most practical pattern out of all the patterns evaluated. Also, in the sketch simulation, the high preference values were observed for a distance of 9 to 12m from the view point to the blockage tree with a D/H ratio of 2. The preference score significantly decreased with the increase of the visual blockage ratio having a turning point at $30{\sim}35%$ of the visual blockage ratio, even though the distance parameters were more important than the visual blockage ratio in the scores. An outstanding view must be handled properly to be preserved or accentuated. Framed, open, enclosed, screened or filtered pattern views should be completely revealed only from their best vantage point, not given away at first glimpse. It this sense, parallax spatial beauty with trees could be improved through the visual aspects of plan arrangements and seems to be an effective design technique for landscape planning and planting design.

Analogy in problem solving is similarity-based reasoning facilitated by verbal and visual operation. This similarity-based reasoning generally supports initial phase of idea search. Therefore, this study intends to infer the types of problem solving by tracing the analogy use of verbal and visual representation through a experimental research. According to the result of this research, the types of problem solving by analogy are classified into 'evolving', 'divergent', and 'poor conversion' type. Firstly, 'evolving type' is distinguished between 'combination type' associated different contents to develope a new design and 'transformation type' associated similar words and sketches to be continuously revised and developed. In these types usually structural analogy rather than surface analogy is used. Secondly, in 'divergent type' associated words or sketches are individually represented, and among them one design solution is selected. In this type usually surface analogy is used. Thirdly, in 'poor conversion type' interaction between verbal representation and visual representation does not go on smoothly, and the generation of idea is poor. In here surface analogy is mostly used. These findings could form the basis of skill development of idea generation and conversion in design education.

In the process of designing a building, the process of expressing the designer's ideas through images is essential. However, it is expensive and time consuming for a designer to analyze every individual case image to generate a hypothetical design. This study aims to visualize the basic design draft sketch made by the designer as a real image using the Generative Adversarial Network (GAN) based on the continuously accumulated architectural case images. Through this, we proposed a method to build an automated visualization environment using artificial intelligence and to visualize the architectural idea conceived by the designer in the architectural planning stage faster and cheaper than in the past. This study was conducted using approximately 20,000 images. In our study, the GAN algorithm allowed us to represent primary materials and shades within 2 seconds, but lacked accuracy in material and shading representation. We plan to add image data in the future to address this in a follow-up study.

BIM(Building Information Modeling) is considered a new paradigm and a powerful method in building design, construction and maintenance. However, it is still hard to implement environmental performance analysis using BIM in design stages. This study aims to reveal practical problems and evaluate interoperability between building design information and performance analysis with case studies. Three case studies are performed using two environmental analysis programs (IES/VE, EnergyPlus) and BIM-based architectural design programs (Revit, GoogleSketchUp) in this paper.

The purpose of this study is to find out the characteristics of users'behavior for the planning of the shared community space(SCS). It was analyzed and estimated that the present status of the SCS of the contemporary multi-family housing sites in Korea and the residents'behavior in the SCS. Theoretic investigation and empirical research methods were used in this study. The empirical survey focused on seeking out user-oriented design criteria, based on the analysis of residents'usage behavior for the SCS. The analysis was made by both quantitative and qualitative methods. The results of this study are as follows; First, as to the usage status survey for the SCS, there is a difference in the degree of usage according to their locations. Second, as to the analysis of the SCS through a mental map, the sketch map analysis is found to be a useful research method for the SCS planning by actualizing the residents'behavior characteristics. In detail, the main characteristics in the SCS planning are nearness, centrality, intimacy, combination of facilities and the connection with the main paths of the complex.

본 연구는 조선 왕릉의 명확한 공간 및 시각구조특성을 활용하여 그 주변 경관관리를 위해 요청되는 시각구조분석의 최적화 모델개발을 모색한 것으로, 이를 최근의 분석 장비와 기법으로 뒷받침하고자 하였다. 연구 결과 삼차원적 정보모델링인 '스케치업'의 간략화한 자료구축을 통해 이 자료상에서 주요지점과 통경축, 그리고 주변의 저해요소 등을 복합적으로 고려한 연속적 시뮬레이션 기반구축의 선행 실시를 상정하였다. 이후 이들의 경로와 시선방향을 연장하는 좌표 값을 도출하고 이 구간을 헬리캠이 운행하면서 촬영한 실사이미지와 시뮬레이션을 상호 비교함으로서 경관분석과 관리의 효율성이 배가될 수 있음을 제안하였다. 이러한 내용은 그간 소수의 국한된 장소에서 촬영된 이미지를 통해 분석되어온 고정적 지각구조 분석방식의 한계성을 극복할 수 있으며, 시선차단요소들과의 관계성 고찰이 용이한 장점을 보유한다. 아울러 제안된 방식은 주요 시선경로 상의 경관적 변화양상을 포착할 수 있으며, 헬리캠을 이용한 실사 이미지와 스케치업의 가상 이미지 간 호환을 통해 최적화된 장비운영을 가능케 함으로서 분석이후 시간적 변화에 따른 정비계획의 시뮬레이션 자료로서도 용이하게 전환될 수 있다. 상기의 제안은 그간의 조망점, 통경축, 경관관리권역이라는 점, 선, 면, 입체적 환경을 중층적, 연속적, 효율적으로 연계하는 자료로서 기능할 수 있을 것으로 판단된다. 본 연구는 조선왕릉과 주변 경관구조 분석방법론 수립에 치중한 까닭에 실천적 점검이 결여된 상태이나 향후 현장에서의 실천과 점검을 통해 기타 문화재의 경관관리에도 응용될 것을 기대한다.

본 연구에서는 먼저 여러 맥락에서 사용하는 '값', '꼭짓점', '높이'에 관해, 그 다음에 지속적으로 사용하지 않는 '겨냥도', '머리셈', '영점 일의 자리/영점 영일의 자리/영점 영영일의 자리', '자릿수', '자연수 부분/소수 부분'에 관해, 마지막으로는 초등학교 교과서/익힘책에서 사용하는 중학교 수학용어 '거리', '수직선', '식의 값'에 관해 논의했다. 이러한 논의를 통해 결론으로 다음의 네 가지를 제안한다. 첫째, 수학용어로서의 '값'을 강조해야 한다. '거리'는 중학교 용어인 바, 초등학교에서는 '높이'를 '선분의 길이'로 통일하는 것을 고려할 필요가 있다. 둘째, 대체 표현이 가능한 '자릿수', '식의 값', '자연수 부분/소수 부분', '각뿔의 꼭짓점/원뿔의 꼭짓점', '머리셈'을 사용하지 않아야 한다. 셋째, '대소수', '진소수'의 사용을 고려할 필요가 있다. 또, '겨냥도'의 사용을 확대할 필요가 있다. 넷째, '수직선'을 초등학교수학용어로 추인하는 것을 고려할 필요가 있다. 또, '소수 첫째 자리', '소수 둘째 자리', '소수 셋째 자리'를 '영점 일의 자리', '영점 영일의 자리', '영점 영영일의 자리'와 동등하게 사용할 수 있어야 한다.

Recently, followed by rapid growth of robotics field, multi-linkage mechanism which can even pass by rough road is getting lots of attention. In this paper, I focused on Jansen mechanism. It's a kinematics object which is named after Dutch artist Theo jansen. Jansen mechanism embraces structure and mechanism which creates locomotion with the combination of the power and simple structure. Theo jansen suggests a 'Holy number'. It's an ideal ratio of leg components length. However, if there's desired gait locomotion, you have to adjust the ratio and the length. But even slight change of the length could cause a big change at the end-point. To solve this problem, I suggest a reverse engineering method to get a ratio of each links by nonlinear optimization with pre-set desired trajectory. First, we converted a movement of the joint of Jansen mechanism to vectors by kinematics analysis of multi-linkage structure. And we showed the trajectory at the end-point. After that, we set desired trajectory which we found most ideal. Then we got the length of the leg components which draws a trajectory as same as trajectory we set, using Multi-objective genetic algorithm toolbox in MATLAB. Result is verified by Edison designer and mSketch. And we analyzed if it could pass through the obstruction which is set dynamically.
